CHARLES WHETHAM, OF SHEFFIELD, ONTARIO, CANADA. TEMPORARY BINDER.

Specification of Letters Patent.

Patented J an. 8, 1907.

' Application filed November 8, 1904. Serial No. 231.890.

To all whom it may concern:

Be it known that I, CHARLES WHETHAM, of Sheffield, in the county of Wentworth, Province of Ontario, Canada, have invented certain new and useful Improvements in Temporary Binders, of which the following is a specification.

The object of my invention is to devise simple and cheap means for changing the cases of temporary binders; and it consists in the construction described in the specification, illustrated in the drawings, and more particularly pointed out 'in the appended claims.

Figure 1 is a perspective view of-a detachable case formed in accordance with my invention. detail of the essential parts of the same. Fig. 3 is a cross section of the device. Fig. 4 is a perspective detail showing a modification of the detachable connection between the metal strip and the holder. Fig. 5 is a perspective detail of another modification of the detachable connection.

In the drawings like letters of reference indicate corresponding parts in the different figures.

'My invention relates particularly to temporary binders for holdin unbound books,

-magazines, and the like w 'ch pass through a number of hands. With such binders it is desirable to frequently change the case or cover for hygienic reasons. At the same time, on the score of expense, it is'not desirable to throw away the binding mechanism, which in ordinary binders is permanently connected with the case.

The case A in my binder will usually-be formed of tough Manila board or paper, thou h of course more expensive material may e employed. This case is formed with a pocket B, running from end to end of its back and provided with an open end or ends.

Through one of these open ends is inserted a metal strip 0. Y D is a holder, in the present case trough sha ed, provided with means whereby a boo or magazine E may be connected therewith. -This holder may be of metal or other suitable material.

In Figs. 1 and 2 I show metal retainingrods F, hinged on the trough at one end and interlocked with the shoulders of a bayonetslot at the other'end. In dotted lines in Fig.

Fig. 2 is an enlarged perspective 1 I show a spring pressing on the back of the book to hold it in proper engagement with the rods F.

Further details of construction are set out in my application, Serial-No. 228,431, filed October 14, 1904.

Detachable connections are provided whereby the holder may be secured to the metal strip C. In Figs. 2 and 3 I show metal tongues G, formed integral with the, strip C. The case over these tongues is provided with long slots at, through which the tongues G may be bent up to a vertical position after the metal strip has been placed in position in the case. Slots b are formed in the back of the trough. D, through which the tongues may be passed and clenched or bent down against the back of the trough, thus securely holding the latter in position. When the cover becomes dirty, the tongues G may be turned up and the trough removed. The tongues are then turned down fiat, when the strip 0 may be withdrawn through the ends of the pocket. The strip and metal trough are then ready for use with a new case, wh1le the old case may be thrown away or destroyed.

I show a modification of the detachable connecting means in Fig. 4.. The metal tongues G in this construction are T-shaped and are inserted through slits in the metal.

strip and flattened down before the insertion of the metal strip into the pocket. Their use is identical with that of the metal tongues shown in Fig. 3. The advantage of this con struction is that the tongues may be made of a specially-flexible metal, and if one of them breaks it may be replaced without the necessity of using an entirely new metal strip.

A further modification is shown in Fig. 5.

In this case notches or slots are formed at the 5 edges of the metal strip C and registering notches or slots in the case and the trough or holder. After the metal strip C has been inserted in the case the metal tongues are inserted as shown. Their ends are then turned up, passed through the slots or notches in the trough, and clenched, securely holding the trough to the case and the metal strip C.

In the various forms illustrated it will be seen that the detachable connecting means are in every case connected with the metal strip C and subsequently engaged with the holder or trough. This is essential in order to make a usable detachable case, as only in this way can the trough be connected and disengaged without destroying or injuring the parts.

' I am aware that strips of metal or other rigid material have been used in the backs of books prior to my invention; but in all cases with which I am acquainted these strips have been permanently bound in and could to not be removedwithout destroying or injuring the connected parts. however, all the ex ensive binding parts are detachable, and 'al that is thrown away when the case becomes dirty is the least expensive part-namely, the paper boards and back.

,By the use of my invention it becomes posslble for magazine-circulating purposes to form the cases'of Manila paper or board and to change them as often as hygienic demands render it advisable. What I claim as my invention is '1. In a binder the combination of a case,

having an open-ended-pocket formed in its 2 5 back; a metal strip inserted in the said pocket and removable therefrom; a holder; and means for detachably connecting the holder to the said metal strip, substantially as described.

- 3o 2 In a binder the combination of acase having an open-ended pocket formed in its back; a metal stri inserted in the said pocket and removable therefrom; a holder provided with means for detachable connec- 3 5 tion with a book; and means for detachably In my invention,

- registered openings being formed and havin connecting the holder to the said metal strip,

substantially as described.

' 3. In a binder the combination of a casehaving an open-ended pocket formed in its back; ametal stri inserted in the said 40 pocket and remova le therefrom; a holder; and metal tongues connected with the metal strip and projecting through slots formed in the case, slots being also formed in the holder throu h which the tongues may be passed. and c enched, substantiall as described,

4. In a binder the com ination of a case having an open-ended pocket formed in its back; a metal strip inserted in the said pocket and removable therefrom; a holder;

in the strip, case and back; and metal tongues engaging said parts and passing through the said openings, substantially as described.

5. In a binder the combination of a case 5 5 having an open-ended pocket formed in its back; a metal strip inserted in said pocket pairs of notches formed in its two ed es; a older; openings formed" in the ho der and case, and registering with the notches in the. metal strip; and transverse metal tongues adapted to be inserted through each set of openmgs in the strip,

cover and back, and bent to secure the latter in place, substantiall r as described.
